Frequently Asked Questions

What is a healthy BMI range?

For adults, BMI under 18.5 is underweight, 18.5–24.9 is normal weight, 25–29.9 is overweight, and 30 or above is obese. These thresholds apply to most adults but may differ for older adults, children, and some ethnic groups where health risks occur at lower BMI values.

Is BMI accurate for athletes?

BMI is a rough population-level screening tool, not a precise individual measure. Muscular athletes often have a high BMI despite low body fat because muscle weighs more than fat. A 200 lb bodybuilder and a 200 lb sedentary person have the same BMI, but very different health profiles.

What is a healthy waist-to-hip ratio?

For men, a WHR below 0.90 is considered low health risk. For women, below 0.80 is low risk. Ratios above 1.0 for men or 0.85 for women indicate significantly increased cardiovascular risk.

Is waist-to-hip ratio better than BMI?

WHR is a better predictor of cardiovascular disease risk than BMI because it accounts for fat distribution. Central obesity (apple shape) carries more health risk than peripheral fat storage.
